While ABC saw mixed results in its effort to keep pace in the Thursday night ratings, CBS continued to get strong numbers from its comedies “The Big Bang Theory” and “Two and a Half Men,” based on Nielsen overnights.

TVbytheNumbers.com reports that CBS muscled its way to a comfortable win for the night in the key 18-49 demo. “Big Bang” was the top show of the night with a 5.3 average rating, even though that number was down from a 5.5 a week ago. “Men” ticked up two-tenths of a point to a 4.2.

CBS’s dramas were also up: “Person of Interest” rose three-tenths to a 3.2 average in 18-49, while “Elementary” ticked up one-tenth to a 2.3.

ABC saw “Last Resort” rebound from last week’s series-low 1.0 average in the 18-49 demo, climbing to a 1.2. “Scandal” also provided good news, hitting a season high with a 2.5, up three-tenths. But “Grey’s Anatomy” equaled its season low with a 3.0, down one-tenth.

The Fox lineup was down, but still good enough for second place overall. “The X Factor” dropped three-tenths to a 2.4 average in viewers 18-49, while “Glee” slipped one-tenth to a 2.1.

NBC spent another Thursday night in fifth place among the broadcast networks, even though a number of its shows were up slightly. “The Office” ticked up to a 2.1 average in 18-49, improving on last week’s series-low 1.9; “Parks & Recreation” rose one-tenth to a 1.5; and “Rock Center” managed a one-tenth improvement to a 1.0. Meanwhile, “30 Rock” dipped two-tenths to a 1.1 and “Up All Night” held steady with a 1.2.

For prime time overall, CBS cruised home with a 3.4 average among viewers 18-49, easily topping Fox (2.3 average), ABC (2.2), Univision (1.5) and NBC (1.3). CBS won by a wide margin in total viewers, averaging 13.9 million to 7.3 million for ABC, 6.6 million for Fox, 3.9 million for Univision and 3.5 million for NBC.
